Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050644, here are decompositions:

13 + 1050631 = 1050644
193 + 1050451 = 1050644
223 + 1050421 = 1050644
277 + 1050367 = 1050644
307 + 1050337 = 1050644
313 + 1050331 = 1050644
337 + 1050307 = 1050644
613 + 1050031 = 1050644

Showing the first eight; more decompositions exist.
